I love my Ninja! It has been wonderful for creating personal smoothies as well as pureeing baby food. I do find it works best if you fill it to, or near, the fill line. If you overfill, it won't work and under-filling will make some of what you're blending stick to the side of the cup rather than blending it in. Overall it is super effective and quick! I haven't met a food the Ninja can't blend.
